Sequela, or late effect, is the remaining or lasting condition produced after the acute stage of a condition or injury has ended. Shelley C. Safian, PhD, CCS-P, CPC-H, CPC-I, reviews the correct way to code for sequelae in ICD-9-CM and ICD-10-CM.

Q: A few days into the patient’s stay, an order for a Foley catheter was placed for incontinence and around the same time the physician documented a urinary tract infection (UTI). Would it be appropriate to query the physician regarding the relationship of the UTI to the Foley? Our infection control department caught this but we did not. I am concerned about this for two reasons; first, I worry about writing a leading query and second, whether the UTI could be considered a hospital-acquired condition (HAC) if additional documentation isn’t provided.
